public static <E> Set<E> checkedSet (Set<E> s, Class<E> type)

Returns a dynamically typesafe view of the specified set. Any attempt to insert an element of the wrong type will result in an immediate ClassCastException. Assuming a set contains no incorrectly typed elements prior to the time a dynamically typesafe view is generated, and that all subsequent access to the set takes place through the view, it is guaranteed that the set cannot contain an incorrectly typed element.

A discussion of the use of dynamically typesafe views may be found in the documentation for the checkedCollection method.

The returned set will be serializable if the specified set is serializable.

Since null is considered to be a value of any reference type, the returned set permits insertion of null elements whenever the backing set does.

<E>    the class of the objects in the set
s    the set for which a dynamically typesafe view is to be returned
type    the type of element that s is permitted to hold

Returns:  a dynamically typesafe view of the specified set
